With hemangiosarcoma, the pericardium fills up with blood due to rupture of the tumor. When the tumor occurs in the skin, a mass or lump can usually be felt in or under the skin. The mass may become ulcerated and bleed. When the tumor occurs in a bone, it can cause pain and discomfort.
More often, cancer cells that break off from the main tumor travel through the bloodstream. Once in the blood, they can go to any part of the body. Many of these cells die, but some may settle in a new area, begin to grow, and form new tumors. This spread of cancer to a new part of the body is called metastasis.Cancer cells have to go through several steps to spread to new parts of the body:. 1  They have to be able to break away from the original tumor and enter the bloodstream or lymph system, which can carry them to another part of the body.hy cancer cells tend to spread to certain parts of the body. Where a cancer starts often plays a role in where it will spread. Most cancer cells that break free from the original tumor are carried in the blood or lymph until they get trapped in the next âdownstreamâ organ or set of lymph nodes.
